4. 13. State of Health estimation of battery systems

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Carl Spångberg; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : This study focuses on estimating the state of health (SoH) of a lithium iron phosphate (LFP) battery system, which is crucial for assessing the value and lifespan of new or used batteries in energy storage, grid support, and electric vehicle applications. A proposed method for determining SoH based on comparing useful and nominal useful capacities in Ah and Wh, as well as total and nominal capacity, has been presented. LÄS MER

5. 14. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring
